Solved

HiI have a project running for the last 2 years: STM32H7, CubeMX for setup.I have 6 ADC channels on ADC3, running in "Regular, non-continous conversion". This works.But now I want to run the application from the external QSPI FLASH. This works almost OK, but the ADC sampling fails: It only samples the first channel in the sequence of 6 channels. The next is never started.I have made no changes to the GPIO setup, except some unused pins, which are configured as analog inputs pr. default in the HAL init. This does not work with the QSPI FLASH interface, because it somehow changes the memory mapping setup in the (bbot)loader. So I just remove the init of the unused pins like this in gpio.c:/*Configure GPIO pins : PA0 PA3 PA4 PA5PA6 PA8 */GPIO_InitStruct.Pin = GPIO_PIN_0|GPIO_PIN_3|GPIO_PIN_4|GPIO_PIN_5|GPIO_PIN_6|GPIO_PIN_8;GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;GPIO_InitStruct.Pull = GPIO_NOPULL;// HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);/*Configure GPIO pins : PB0 PB1 PB2 PB10PB11 P

Hello, I am using STM32H7 with a circular display (driver HX8363-A). One of the problems that I seems to have is that although on the TouchGFX software the content looks nice, the moment I display that same content on the physical display, it looks horrible. Every component that I tried displaying has very sharp edges and thus I suspect it has something to do with anti-aliasing not being turned on (see the picture). Is there a way to enable anti-aliasing or do you think this is something else?I know that the display that I am using CAN look normal, since I confirmed this by using the display manufacturers devkit, which however runs on Android OS. 

Hello,Please help me with the solution.I have a product with STM32H723ZGT MCU as a core. For device production I need to set Read Out Protection (RDP) Level 2 option bytes which would protect the devices debug port. To program the RDP byte, I use STM32 HAL's flash API. Unfortunately, after the function HAL_FLASH_OB_Launch() device enters a special state and the only way to reset the application is power reset (POR). The problem with that is my product has an on board battery which has been soldered during the manufacturing process before programming. I have found a possible solution, which is described in this video: https://www.youtube.com/watch?v=f7vs0NwZPFoI have even tested this solution with STM32L4 series MCU and it worked fine. Unfortunately, the same approach with the STM32H7 series did not work. Any suggestions?

Hello everyone, I work in a team where we manufacture an electric car. We currently use Arduino Mega as our ECU, but we want to shift to STM. We already have a STM32-L152RE Nucleo board. I am not able to run any sort of program on the board. The code gets uploaded but never runs. What might be the potential issues, is there any specific method to upload the code to this particular Nucleo board.

Hey!I initialized the TIM1 peripheral to output an complementary PWN signal on channel 2 (PB14) and tested it with an oscilloscope. Signal is present, everything's fine.Then after initialization of the SPI2 peripheral (PB13 & PB15) PWM signal is no longer visible on pin. I use CubeMX for code generation and specific line where PWM output "dies" is this: void HAL_SPI_MspInit(SPI_HandleTypeDef* spiHandle) { ... __HAL_RCC_SPI2_CLK_ENABLE(); // <- here ... } I can toggle SPI2EN bit inside APB1ENR register in Debug mode and see the same outcome:Now I'm lost what to do next. PCB is already made and I need both TIM1 and SPI2. Workaround in my case would be hand-written SPI which I try to avoid of course.Any suggestions?Thanks.

Hello,I'm measuring Channel AN11 (Pin PB10) and the internal Temperature of the CPU of my STM32G071RB Nucleoboard via DMA. DMA is necessary, because later on the project will scale a lot. I really hope, someone has a good solution for this. When changing the voltage on AN11, the internal Temperature Value also changes. Here Some Examples:Raw Value of AN11Converted Temperature of CPU in °C70-10474-106819-251449231924472170343288314001/ 409530My Configuration is this:  /* * ADC.c * * Created on: 10.08.2023 * Author: scheichpa */ #include <CubeMX_ADC.h> ADC_HandleTypeDef hadc1; DMA_HandleTypeDef hdma_adc1; /** * @brief ADC1 Initialization Function * None * @retval None */ void MX_ADC1_Init(void) { ADC_ChannelConfTypeDef sConfig = {0}; /** Configure the global features of the ADC (Clock, Resolution, Data Alignment and number of conversion) */ hadc1.Instance = ADC1; hadc1.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV2; hadc1.Init.Resolution = ADC_RE

HelloIn the new version of Yocto release mickedore, SIGN_TOOL variable needs to be specified to sign TF-A binary which should corresponds to STM32CubeProgrammer signing tool https://wiki.st.com/stm32mpu/wiki/Signing_toolPractically, how can we set the the variable to the STM32CubeProgrammer signing tool? Is there a Yocto recipe native that include this tool?https://github.com/STMicroelectronics/meta-st-stm32mp/blob/mickledore/recipes-bsp/trusted-firmware-a/tf-a-stm32mp.inc#L296Thanks 

Hello,I followed the STMicro YouTube tutorial for developing an external QSPI loader. I am using the W25Q128 attached to the NUCLEO-H7A3ZI-Q. The flash is working fine with my driver using the test program "main_test.c" provided with the tutorial, and I can access the flash contents at 0x090000000 in memory-mapped mode from the STM32CubeIDE debugger. I compile the external loader with the linker script provided in the tutorial and move the .stldr file into the external loader folder for STMCubeProgrammer. I select my loader from the list of loaders, but when I try to view external flash contents at 0x090000000, I get data read failed. If I try to download data to the external flash from STMCubeProgrammer I get:16:35:41 : Time elapsed during the read operation is: 00:00:00.00916:35:50 : Memory Programming ...16:35:50 : Opening and parsing file: testbinary1M.bin16:35:50 : File : testbinary1M.bin16:35:50 : Size : 1.13 MB16:35:50 : Address : 0x0900000016:35:50 : Erasing memory correspondin

Hi,I bought two same board and use one to test.After upgrade stlinux on this testing board, the cpu it can recognize is only one when the other one can recognize it two.could you give me a guide to fix it and why this happened?Thanks.

Hello,The STEVAL-SMARTAG1 firmware has been very helpful - however the .zip file does not contain the CubeMX file - just the generated initialization code.Would it be possible to obtain a copy of the original CubeMX .ioc file please?Thanks,Evan

    I have made a custom pcb of STEVAL-ISV019V1  circuit. In that ,we need to charge 3.7v lithium ion battery via USB supply and solar panel. When I connect USB supply or panel voltage as input voltage  the complete input voltage is coming in the battery charging point. where as the lithium battery can only  be charged  up to 4.2V.when I measure the open voltage at battery charging point it appears greater than 4.2V.How can we set the charging voltage  and also how can I measure the open voltage at fully charged condition?

Hello everyone,In my sample project I have created, RTC does not perceive certain months as 31 days. Although it is 31 days in July, October, December, I took the same result in my essays with a code sample with an RTC code.I don't have problems in January, March, and August.What are your ideas? July 30 -> 01 august (Problem)Func:HAL_RTC_SetTime(&hrtc,&updateTime,RTC_FORMAT_BIN);HAL_RTC_SetDate(&hrtc,&updateDate,RTC_FORMAT_BIN); Card I used: F407VG 168mhz 

Hi,I use STM32CubeMx 6.9.1 on a STM32H563 project. Programming the I2C pins, there is no way to setup the I2C_SCL pin as Alternate PushPull. Only the Alternate Open Drain is possible. Why?In my application, the I2C_SCL pin is connected to a serial EEPROM, and in my opinion there is no reason to not have this possibility.Or I forget something? 

Hello.I am trying to establish a USB CDC connection with a Windows 10 computer using the STM3210E-EVAL. I can't get it to work. After starting, I connect the board to the PC via USB and the following message appears in the device manager:   Is there a small example somewhere that shows how data is received and sent via USB-CDC?Thank you, and greetingsRasmus

I have a custom board with a stm32mp151c and 256M DRAM.Trying to get optee 3.12 from ecosystem 3.0.0 to start.Everything works fine with tf-a 2.4-r1 and sp_min, u-boot 2020.10 etc.But I can't get optee to start. I've enabled a high loglevel and the last print I get from optee is:...I/TC: Pager is enabled. Hashes: 2208 bytesThen everything goes quiet. No stacktrace, fault, or anything else. Just "dead".To me, this looks like some very basic issue with DRAM sizes etc. But I can't say for sure.My dts looks correct with memory regions and declarations.But I noticed that in the build conf.mk was getting some weird stuff.CFG_DRAM_SIZECFG_SHMEM_STARTCFG_TZDRAM_STARTThese three had some wonky values for a 256M board. And they seem to be used?So my conclusion is that it does not suffice to set dts properties for optee, some tweaking of platform memory sizes (looks like there are options for 512M 1G etc, but not 256M) needs to be done.Anything else that needs to be fixed for a 256M board?Maybe t

Hi, i'm realative new to using ST products and i'm currently trying to debug with the STM32F205RCT6 using the ST-LINK V2 with the debug protocol SWD. but it's simply not worinking, it keeps saying No device found on target.  This is how it's connected:- PIN 19, 32, 48 and 64 to the 3,3V- PIN 18 and 63 to the GND- PIN 7 to the RST- PIN 60 to the GND- PIN 49 to the SWCLK- PIN 46 to the SWDIO (this one is connected with a pull-up resistor of 100k ohm)- PIN 60 to the GND (and tried to 3,3V)- PIN 28 to the GND This is what i have tried so far in order to have it to work:-checked with the osciloscoop if and a PCBite to see if the signals for clock and data to go the exact pin of the chip-checked with a multi meter if the pins are getting power.-replace the MCU with another one  Plz take a look at the photos i have attach. i have a felling that i have done something wrong and i don't know what it is. if there is more information needed let me know.  

Hi, I am working on a project with STM32H730. Due to layout limitations, we'd like to use TIM2 channels 3 and 4 rather than 1 and 2 for encoder mode if possible. Is this possible?

I am trying to configure the TIM5 to get timestamp in milliseconds for a long period (over 40 seconds).Here is the current configuration of TIM5:// This function inits and start the timers usedvoid timer_init(void) { __HAL_RCC_TIM5_CLK_ENABLE(); TIM5->PSC = (HAL_RCC_GetPCLK1Freq() / 1000000) - 1; TIM5->CR1 |= TIM_CR1_CEN;}We did observed an overflow problem after about 40 seconds, our timeout were taking for ever to expire after the first 40 seconds. So we did use this test code to gather data:snprintf(printbuff, sizeof(printbuff), "Timer 5 ARR %X PSC %X CR1 %X CR2 %X EGR %X RCR %X\n",                                       TIM5->ARR, TIM5->PSC, TIM5->CR1, TIM5->CR2, TIM5->EGR, TIM5->RCR);send_uart(printbuff, strlen(printbuff));while (true){    uint32_t mltime = TIM5->CNT;    HAL_Delay(1000);    uint32_t mctime = TIM5->CNT; 

Hello,I am developing a system using VL53L1X.I have read UM2510 (A guide to using the VL53L1X ultra lite driver).This library implements the function called "StartTemperatureUpdate".The description for this function states, "This function performs the temperature calibration."The function declaration is written as:  VL53L1X_ERROR VL53L1X_StartTemperatureUpdate(uint16_t dev);  I'm curious as to why this function doesn't require the actual temperature as an input.The mechanism of temperature calibration, please let me know.It would be helpful if you could introduce related documents and URLs for reference.Best Regards. 

Hi, I'm testing some VL53L4CX for about 10 months with nrf52832 using I2C. It's used in very dark conditions and within 3m and I take 15 measures 24 times a day.Between periods of measures I completely power off the sensor with an LDO.It works fine for long period (1 month or more) and sometimes it starts a long period of consecutive bad measures.(15 measures with status <> 0). It can last more than one week and it comes back to normal for several weeks...I used the example of SimpleRanging code in app_tof.c only adapted for nrf52:- power on + I2C_Init + MX_TOF_Init + MX_TOF_Process + MX_TOF_DeInit + I2C_DeInit + power offMore than once, I just put the device in ambient light and it resumed the correct measurements...Questions:- How is it possible that it seems to stay in bad configuration despite of powering off the sensor?- Is it a way to reset to factory values when I have bad measurement?Thanks for your answers.  

I have PM-SMPSM motor that I'm trying to get to spin with the STSPIN3201 - I seem to be able to configure the project in the MC workbench, generate code, and load it onto the micro through CubeIDE just fine - but no matter what I do, the motor moves slightly when I try to spin it up, and the rotor locks in a fixed position.  More specifically, it seems to on first boot do a search to determine the encoder/winding relationship by doing a short ramp, but then it does the rotor lock every time I request a speed.  The rotor isn't locking in a fixed position, but it seems to be cogging to one of several fixed positions and locking there.  Things I have tried:I have confirmed that the encoder is working by spinning the motor manually and watching the speed, plotted by motor pilotI have changed the phase winding order of the motor, trying each possible phase wiring in turn, just to make sure it's not just commutating incorrectlyI've plotted current on the scope, it looks ok in

Hi,LWIP: what is the difference between udp_send() and udp_sendto()?What are the use cases for each? The LWIP_RAW_CLIENT ECHO uses udp_send() but also uses udp_connect. Whereas udp_sendto() does not need to connect?Does anyone have example? Thanks

When I try to communicate my STM32L4P5-DK through SPI protocol. I fed the MOSI and SCK pin to the oscilloscope and checked the output there I got several doubts1) when I send a data 0xAA to the slave ( HAl_SPI_Transmit(&hspi2,0xAA,1,10) ) with the baud rate of 187.5kBits/sec the time period was 5us app(each bit is shifted at falling edge as per my configuration) but here MOSI otput is not as expected      2) when I try to send 0xFF the expected MOSI output is the MOSI pin should remain high for 8 falling edges of SCK but it was not that I got on the scope.The below picture shown the 0xFF data in  MOSI(Yellow) and SCK (Green) 3) also the SCK is not a continuous signal, SCK  maintains 0 for each 8 cycles with a regular period of time why? 

We are using the STM32MP157AABx device in our project and updating to the v5.0 Ecosystem and STM32CubeMX v6.9.0.When we generate our device tree files, the optee-os device tree tries to include:#include "stm32mp15xxab-pinctrl.dtsi"This file is not found in the optee-os-stm32mp v3.19.0 source tree referenced in the v5.0 Ecosystem.I have had to manually modify the dts to include:# include "stm32mp15xxac-pinctrl.dtsi"This is the closest match, but not equivalent to the number of gpio banks in the AABx package.Is this an issue with optee-os-stm32mp source code, the CubeMX tool, or user error in our configuration?
